This is a two-page lithograph featuring the Cepheid Variable Star RS Puppis, an example of a special class of bright pulsating stars whose light and energy outputs vary over a set period of time. The text on the lithograph explains the historic...(View More) importance of Cepheid variable stars as distance markers. The accompanying classroom activity In Search of … Cepheid Variable Stars is a curriculum support tool designed for use as an introductory inquiry activity. During the classroom activity, students use the images and text on this lithograph to generate questions about Cepheid variable stars. They will conduct research to answer their questions and will create a presentation to demonstrate their understanding of the material, providing supporting evidence from their research.(View Less)

Emphasizing the synergies between science and engineering, these video clips highlight the research of professional ocean scientists and engineers in various disciplines. The clips are accompanied by additional relevant content including images,...(View More) data visualizations, graphs, animations, and other information. Content has been organized into more than a dozen thematic areas such as Solving Old Problems with New Technology and Small Scale Observations and Large Scale Ideas. All content has been aligned with science and engineering practices from the Next Generation Science Standards, including "asking questions and solving problems" and "planning and carrying out investigations," providing applicable resources for teachers who want to provide role models of effective practice for their students.(View Less)

This series of laboratory lessons and activities uses authentic solar imagery and data to introduce students to solar science. Students are asked to explore details in imagery, including how to deal with the issues of noise and resolution, and...(View More) understand scale. They are introduced to the concept of space weather and how that affects both observing instruments and the Earth. Students learn about spectra, how helium and coronium were discovered, and go on to explore real spectra from the Sun. Most activities are mathematically based, and targeted for grades 9-10. Imagery is included from NASA/ESA's SOHO mission, NASA's SDO mission, and Japan's Hinode satellite.(View Less)

This is an activity about scale. Participants will arrange imagery of Earth and many other space objects in order of their size from smallest to largest, their distance from Earth's surface, their temperature from coolest to hottest, and/or their...(View More) age from youngest to oldest. By manipulating these images and discussing their ideas, children and adults represent and confront their own mental models of space and time.(View Less)

This is a set of three activities about how scientists study other worlds. Learners will explore and compare the features of Mars and Earth, discuss what the features suggest about the history of Mars, and create a model to help them understand how...(View More) scientists view other worlds. The activities help to show why scientists are interested in exploring Mars for evidence of past life, and address the question: "Why are we searching for life on Mars?" It also includes specific tips within each activity for effectively engaging girls in STEM. This is activity 4 in Explore: Life on Mars? that was developed specifically for use in libraries.(View Less)

This program uses NASA data and resources to promote authentic classroom research experiences. These two complementary guides lead students through the process of conducting their own inquiry-based research on an Earth-focused topic. In their...(View More) guidebook, students read content and answer questions about each step in the research process- from formulating a question to sharing results. The separate guide for teachers provides explicit instructions, lists the standards addressed, and includes additional hints, resources and websites.(View Less)

The emphasis of this lesson is deepening students' understanding of how and why we measure precipitation across the globe. Students will look at NASA Tropical Rainfall Measuring Mission (TRMM) data gathered during hurricanes and how this data can...(View More) prove essential in helping scientists forecast the amount of precipitation. Students will also learn how the Global Precipitation Measurement (GPM) Mission is enabling scientists to collect new information on hurricanes. The lesson uses the 5E instructional sequence.(View Less)

This is an activity about Lunar samples. Learners will see snapshots of the Moon's history and hold an important artifact of American history with a Lunar Sample Disk. Earth rocks and soil of similar types as the lunar samples may be provided and...(View More) explored with hands, eyes, noses, and tools. Please note, checking out a Lunar Sample Disk requires training, a secure storage facility, and a minimum of a 6-week lead time. This activity is part of Explore! Marvel Moon.(View Less)

This Science On a Sphere (SOS) module is designed to help the public better understand the story of water on Mars and how we're learning more about it. It portrays the mystery of what happened to the water on Mars in the context of a detective...(View More) story. NASA's MAVEN mission (Mars Atmosphere and Volatile EvolutoN) will help solve this mystery by studying the Martian atmosphere, how it has changed over time, and how it interacts with the Sun and the solar wind. The module also delves into Mars exploration, featuring past, present, and future Mars missions, and includes an activity comparing images of water-related features on Earth and Mars. It will help people understand that a planet's climate can change over time and how learning more about Mars helps us learn more about Earth and other planets as well. Resources included are: script, SOS playlist and datasets, background and tips for the docent or facilitator, and image comparisons of water-related features on Earth and Mars.(View Less)

This is a lesson about generating hypotheses and testable questions. Learners will use critical thinking and a collaborative approach to pose questions related to the study of Mars and evaluate the quality of their questions. They will explore...(View More) remote-sensing data collected by a camera orbiting Mars - the Thermal Emission Imaging System (THEMIS) and develop a team science question. Students will practice critical thinking skills, use a collaborative approach to this first critical step of the scientific process. Exploring the images of the surface of Mars in Visible (VIS) images, students will come up with a topic of study, their team science question and hypotheses. The lesson models scientific inquiry using the 5E instructional model and includes teacher notes and vocabulary.(View Less)
